DANA I-I. BENJAMIN, OF LEBANON, PENNSYLVANIA.

DAMPENING-MA CHINE Application led August 12, 1905.

To all whom it may concern.'

Be it known that I, DANA H. BENJAMIN, citizen of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Dampening Machines, of which the following is a speci'lication, reference being had therein to the accompanying drawing.

My invention relates to an improved dampening machine, and I declare that the following is a full, clear, concise and exact description thereof sufficient to enable one skilled in the art to make and use the same, reference being had 'to the accompanying drawings in which like letters and numerals refer to like parts throughout.

My vinvention is applied to a class of inachinery which is used in laundries for dampening collars, cuffs and similar articles before ironing them, and among the particular features of the invention is the application of heat to the surfaces of moistened aprons having the goods between them so that the goods are dampened evenly from both sides at once and as rapidly as they can be passed through the machine, the dampening members of which can be regulated for the most satisfactory work. The heat drives the moisture instantly through the goods making them perfectly and evenly dampened.

I do not attempt to state all the advantages of my invention, as they will appear from the application and will be apparent to those skilled in the art.

In the drawings, Figure 1 is an end view of my machine, and Fig. 2 is a cross-section view in the same position. Fig. 3 is an opposite end view, while Fig. 4 is a front view.

The various details of construction will be apparent to any practical machinist and will be comprehended from an examination of the drawings.

The frame of the machine is represented by A and comprises side plates and standards or legs. The side plates can be suitably connected by bars or stays as may be desired. The machine comprises two heated cylinders, stationary or movable, or other mechanical construction whereby heat may be applied to the surface of the moistened aprons, together with rollers. The cylinders are shown by B and C respectively and are supported on suitable journals at each end. At one end, as seen in Fig. l, roller B has a gear B1 Specification of Letters Patent.

mounted to mesh with the worm B2 which is turned by means of power applied to pulley B3 adjacent to which is an idle pulley. On

the end of the cylinder, shown in Fig. l, is`

mounted a gear B4 which meshes with gear C1 on cylinder C. At the other end'of the cylinder B is mounted, as seen in Fig. 3, gear B5, and on a corresponding end of the cylinder C is mounted gear C2.

The rollers are arranged in two sets and are designed to pass around and 'between the rollers of each set a cloth or other suitable apron. The rollers of the upperl set are shown by a, l), c, d, e, f and g, each of which is supported on a proper journal at each end of the frame of the machine as indicated by al, b1, c1, d1, 61,]'1 and g1.

E represents a tank partially filled with water in which roller e is immersed. The cloth which is used on the upper rollers is indieated by F, Fig. 2, in which the arrows in. dicate the direction of travel, and it willbe .seen that it passes around the various rollers transmit power from the roller c to roller el. l

As will be seen in Fig. 3, roller d is mounted.

` in a bearing at each end made up of two parts,

the outer one, d2, being adjustable by wheel and screwl ,shaft Z3 to regulate the relative sol position of rollers c and CZ and the amount of moisture to be left in apron F. In order to adjust the tension of apron F each journal which supports roller l) is mounted on bracketarm b2 adapted to slide up and down on standard h3 and adjusted by screw and wheel b4.' In order to make the adjustment perfeet, horizontally as well as vertically, and to keep the apron running true without any creeping toward either side the journals b1 are slidably mounted on brackets h2 and have notched arms b5 extending across the standards b3 which has thereon lugs l2 to engage with the notches and hold the journals-in proper horizontal position.

Referringto the lower apron F which travels in the direction indicated in Fig. 2, it is supported on rollers 7L, i, j, 7c, Z, m and n suitably supported on journals h1, il, jl, 761, Z1, fm1 and nl; the other roller y'being actuated by gear thereon from gear B5 and in turn actuating roller 'i in the same manner las,V the roller cis actuated. f

E represents a tank partially filled with liquid and in which roller 7c is partially subhaving the bearing i2 at each end adjustable by means of the wheel and shaft 'i3 to pressV superiiuous moisture from the apron F after it comes from the bath. This apron also passes around cylinders B andC, as indicated. The roller m has its journals mounted in a forked arm M which is pivotally mounted on bracket M which is slidably mounted on the arm M to be moved up and down by screw m2, the raising or lowering of which effects tension on the lower apron F The bracket. M is mounted about the middle of the machine, and the forked support M for the roller m extends forwardly to handle ma so that the swinging of the forked arm is effective to keep the apron in true course as'fit passes around the rollers and cylinders.

The design and scheme of my invention is to feed steam or heating medium through the cylinders B and C, as indicated, through ordinary stuffing boxes N and N. The goods are fed into the machine from the shelf O and pass between the dampened aprons, as indicated in Fig. 2, around the heated cylinder C which dampens one surface and thence around the cylinder B which' dampens the other surface and then outward onto shelf P.

By the means illustrated I practice the method which is included in my inventionl and whlch consists in dampenmg fabrics .for

f ironing by applying moisture 'first to aprons which are dampened evenly and to the desired degree after which heat is applied to the aprons converting the moisture of the aprons into vapor which instantaneously penetrates the fabrics that are fed therebetween and from each side thereof. This insures the even dampening of the fabrics to the proper degree, the fabric being fed to the aprons and carried by and between them to t e heating members and passed around the y.

each face of the fabric thereto andjbeing delivered by the aprons from the-machine Y f f I have merelyillustrated one method of "applying my invention and do not desire to merged to dampen the cloth. The roller iis* f Ybe mounted in the same way as is roller (Z'above,

imite'd'to the details of such showing.

l'Having described my invention, what I claim as new, vand desire to secure by Letters Patent, is:

1. Ina machine of the character described, aplurality of rollers arranged ,in two sets, each set including a dampening roller, a roller adjustably niounted and a heated cylinder, and an endlessl'apronvmounted on jeach set fof rollers, 'tl'ievtwo heated cylinders'being mounted with theirjsurfaces adjacent with the apronsftherebetween, and beingjinounted to rev'olye in opposite directions whereby to applyheat to each side of a fabric carried by'fsaid .aprons substantially as shown and described.

2t In a machine of the character described, roller members arranged in series, heatapplying cylinders and an apron on each series lof rollers and mounted to pass together around one cylinder in one direction of revolution, between the adjacent surfaces of the cylinders and therefrom around the other in the opposite direction of revolution, andv means for moistening the aprons to a desired degree whereby fabrics fed between the aprons may be evenly and instantly moistened from each side,`substantially as shown.

3. In a dampening machine having heating cylinders adjacent each other and rollers for carrying dampening aprons, dampening aprons mounted to be carried on the rollers and carried around the major part of each cylinder and disposed parallel-to each other for a distance before and behind said cylinders to carry fabric to and from the same, substantially as described.

In testimony whereof I afIiX my signature in presence of two witnesses.

DANA H. BENJAMIN.
